Application filed May 10,

This invention relates to new and useful improvements in scrapers, and particularly O'ne object of the invention is to provide a device of this character which can be manufactured and sold at a low cost, and wherein the ordinarily discarded safety razor blade 1o ma 7 be used to great advantage.

1 nether object is to provide a device of this character wherein the'scraping blade may be easily and quickly shifted to such a position that the device may be carried in the pocket,

.15 without danger of cutting the hand when the hand is placed in the pocket and comes into contactavith the device.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a perspectiveviewof the device, the blade being in position for scraping.

Figure 2 is a vertical sectional view on the line 22 of Figure 1-.

Figure 3 is a similar sectional view showing'the blade shifted to its position which permits the device to be safely carried in the pocket.

Referring particularly to the accompanying drawing, there is shown afiat metal plate 10 having a handle portion 11 extending from one of the sides thereof,- and being formed integrally therewith. Carried by theplate 10, and projecting from one face thereof, are the two rows of transversely alinedstuds 12 and 13, the latter being arranged inwardly of the former. The pins or studs 12 are spaced apart to the proper distance to be received in the terminal openings of a safety razor blade, of the Gillette type, the pins-or studs 13 being similarly spaced, and for the same purpose. as will be explained later herein. Forlncd in the intermediate portion of the plate 10 is a slot 14, one end of which lies be tween the studs 12, while'the other end lies between the studs 13. Disposed through this slot is a bolt 15, the head of which bears against the face of the plate, while the threaded end thereof passes through thecentral opening of the razor blade 16, to receive thereon ja clampin nut 17 Which'serves to tightly clamp thefiilade against the plate, with one of its cutting edges projecting to the proper degree"beyond the outer end of the 1928.

said plate. In this position the device is adapted for use, as 'a scraper, the operator grasping thehandle 11 and-engaging the cutting edge of the blade with the surface to be cleaned, whereby to remove such matter as i has dried or hardened on such surface. To

permit the device being carried in the pocket,

without danger of cutting the fingers, the operator loosens the nut 17, until the blade can be disengaged from the studs 12, slides the blade inwardly so as to engage the studs 13 in the terminal openings of the razor blade, andthen screws up on the nut whereby to clamp the blade against theplate. The blade is thus positioned with its outer or cutting edge inwardly of the outer end of the plate 10, thereby protecting the hand of the owner from contact with such cutting edge, when placing the device in his pocket or removing same therefrom.

It will be noted "that the length of the outer edge of the plate 10 is the same as that of the cutting edge of the razor blade, so that when the blade is shifted to the position of Figure 3.-the entire cutting edge is disposed within the contour of the plate. There will thus be no small portion of the cutting edge projectmgfrom the plate to cut the owners hand. v hat is claimed is:

1. A scraper comprising a base having a plurality of studs projecting from one face thereof, a blade havingopenings receiving certain of the studs to position the blade with its cutting edge projected beyond an edge of the base, and for receiving others of the studs to hold the blade with its cutting edge inwardly of said edge of the base, and a clamping means for holding the blade in either of its positions, and for supporting the blade while making the shift from one position to the other.

2. A scraper comprising a base having a plurality of transversely extending rows of studs, a blade provided with openings receiving one row of studs whereby the cutting edge-of the blade will project beyond an edge of the base and adapted to receive the other row of studs whereby the cutting edge of the a plurality of series of studs and a slot intersecting the series of studs, a cutting blade arranged to be engaged with one series of studs whereby to hold the blade with its cutting edge beyond, an edge of the plate and to be engaged with the other series of studs to hold the blade with its cutting edge inwardly of said edge of the plate, and a headed clamping stud disposed through the blade and slidable in said slot for clam )ing the blade on the plate and for manipulation to shift the blade from one series of studs to the other series of studs.

In testimony whereof, I afiix my signature.
